pipe of a gas engine to which the water volatilizing chamber 6 is attached. My invention resides in the construction and application of this volatilizing chamber 6 'to the engine, and for the purpose of illustrating and describing my invention, drawing is confined to an illustration of the said volatilizing chamber and its application. This chamber comprises an outer tubular housing 7 and a valve sleeve 8, which is received in the outer housing 7 the forward extremity of the latter being open to' therein. The inner receive said valve sleeve extremity of the tubular housing 7 is pro. vided with a screw plug? integrally formed therewith adapted to e threadedinto an opening 10, which is formed in the exhaust pipe 5, thereby providing means for attach ing the device to the exhaust pipe of the engine in such position that the heat of the said exhaust pipe is employed for volatilizing water which is introduced into the chamber 6 from a source of water supply in.

the manner hereinafter to be described. The outer extremity of the valve sleeve 8 is closed to the outer atmosphere, while the inner extremity thereof is openand abuts against the inner extremity of the housing 7.. Thus, the water volatilizing space is formed on the interior of the valve-sleeve 8, the said space being housedby the valve the sleeve 8 and the latter being in telescoping relation with the housing 7 The valve sleeve 8 is revolubly mounted in the housing 7, and the same is machined to snugly fit into the housing 7.

An induction pipe 12, which is in communication with the radiator of the engine,

or other suitable source of water supply, is

in communication with an induction port 13 in .the housing 7, the said induction port 13' adapted to register with an induction port 14 in the valve sleeve 8. An eduction pipe 15 is in communication with an eduction port 16 of the housing 7, which said eduction port 16 is adapted to register with an eduction port 17 of the valve sleeve.- The 15 communicates with the cylinders of the engine, whereby the volatilized water is conveyed, or injected into the latter through said pipe. A bolt 18 is passed. through the outer extremity of the valve sleeve 8 and the inner extremity of said-bolt is threaded into the inner end of the housing 7, as shown at 19, thereby connecting the only suflicient to register the valve sleeve 8 in fixed relation with the said housing 7. The outer extremity of the valve sleeve 8 is provided with an annular flange 20 thereon, which extends beyond the circumference of the said valve sleeve and engages with the outerextremity of the housing 7. The periphery of this annular flange 20" is provided with a gap 21 therein, in which is received a pin 22 projecting from the outer extremity of the housing 7. Thus, the valve sleeve 8 can only be rotated the length of the said gap 21, the pin 22 forming a stop to further rotation thereof. This. rotary movement I 15 For the purpose of operating the valve extremity of the latter,

to entering the opening 31 as a result of the influence of sleeve 18, an operating member-24 is connectedratione extremity with an ear 25,

formed on the periphery of the annularj flange 20, the said operating member 24 being extended through a guide-member 26 into convenient reach of the operator of the engine. This guide member 24 is integrally formed with the housing 7 near the outer as shown at 27.

12 is controlled by The. induction pipe 28, which is threaded means of a valve piece into the said induction pipe, as shown at 30, whereby the flow ,of Water through said pipe into the 'valve sleeve 8 is regulated according to the proper amount to effect the best results.

The inner extremity of the housing 7, adjacent the exhaust pipe 5, is provided with an air induction opening 31, which the heat from the exhaust P p i Now, assuming that the valve piece 28'is in open position and that the ports 13 and Hand 16 and 17 'are in registering positions, water will flow through the ports 13 and 14 into the valve sleeve 8, wherein it will be volatilized under the temperature of the said chamber, due to the influence of the heat from-the exhaust pipe 5. This .volatile Water will tilizing chamber 6 through the registering eduction ports 17 and 16 and pipe 15 into the cylinders of the engine, Where it is propcrly mixed with the carbonaceous fluids, the volatile water being injected into the cylinder slightly in advance of the carb0- naceous fluid, or compound.

By placing the v'iflatilizing chamber 6 in i and that nowpass from the volaclose proximity to the exhaust pipe 5, the heat of the latter maintains a relatively high temperature in the vicinity of said chamber sufficient to instantaneously volatilize the Water on entering the said chamber.

While I have described and herein a specific foriji of my understood that, ,I'

illustrated invention, it is am-not limited thereto the same. may be modified and varied Withoiit'departing from the spirit of t e invention, or the scope of the appended claims.

Having thus described what I claim and desire Patent is',
